Gadiformes is an order of ray-finned fish, also called the Anacanthini, that includes the cod and its allies. Many major food fish are in this order. They are found in marine waters throughout the world, and there are also a small number of freshwater species.

Common characteristics include the positioning of the pelvic fins (if present), below or in front of the pectoral fins. Gadiformes are physoclists, which means that the gas bladder does not have a pneumatic duct. The fins are spineless. Gadiform fish range in size from the codlets, which may be as little as 7 centimetres (2.8 in) in adult length, to the Atlantic cod, Gadus morhua, which reaches up to 2 metres (6.6 ft).[1]
